Haizea has been played over 10 times on NTS, first on 16 August 2017. Haizea's music has been featured on 12 episodes.

Haizea were a five-piece Progressive folk group from the Basque region of Spain. Their sound could be described as psychedelic electric folk, the instrumentation comprised guitars, bass, drums, flute, assorted percussion, and the beautiful voice of Amaia Zubiria.

Haizea released two albums; The self-titled "Haizea" - 1975, is a more conventional psych folk ballad oriented album with lovely male/female vocal harmonies.

"Hontz Gaua" - 1976, is regarded as a masterpiece of cosmic/acid folk music.This is one of the holy grails of European folk/psych in the same league as the Carol Of Harvest and the Emtidi albums. Superb deep mystical cosmic folk psych recorded in super HIFI quality with a crystal clear sound. Strange percussion, echoed guitars, cellos, flute and stunning female vocals with long tracks. As Dag Erik Asbjørnsen, author of the "Scented Gardens of the Mind" puts it: "Honts Gaua simply gorgeous, on of the best progressive folk albums in the whole Europe. The Basque group is little known but deserves wide acclaim for this work of art!"

Both albums were released on the Elkar label, based in Bilbao, which has played a major role in Basque cultural revivalism.
